Well, since each of the 171,000 would have been charged with illegal immigration, that's more than half of your total criminal charges right there. But 265,000 sounds scarier than 94,000, so I get why you did that.
Not too concerned about arrest numbers; between confusion over identity (they're undocumented, after all), and at least a few cases of profiling here and there, there's probably many cases where they got the wrong guy. Not to mention that, as you like to point out in every discussion about alleged sexual assault, innocent until proven guilty.
While I know you'd like us to think that means that 219 of those individuals were murderers, I'm guessing that a smaller number of them committed multiple murders. Ditto with the other crimes.
Combine that with the fact that an estimated 1.5 to 2 million undocumented people live in Texas, well, that means that the vast majority of them aren't criminals.
